English Abstract

A storage rack includes front and rear deck beams and C-shaped tie supports extending between the deck beams. Each tie support has a side wall, a top flange and a bottom flange. The top flange has front and rear ends and tabs extending downwardly therefrom. The bottom flange has front and rear ends and tabs extending downwardly therefrom. When assembled with the deck beams the front and rear ends of the top flange are seated on a support ledge of the deck beams with the tabs received into respective slots. Similarly, the front and rear ends of the bottom flange are seated on a lower leg of the front and rear deck beams with the tabs received into the respective slots. The tie supports cooperate with the deck beams to limit the sagging of the decks, while also preventing outward twisting of the bottom flange of the deck beams.


French Abstract

Une étagère de rangement comprend des barrots de pont avant et arrière et des supports dancrage en forme de C qui sétendent entre les barrots de pont. Chaque support dancrage possède une paroi latérale, une bride supérieure et une bride inférieure. La bride supérieure possède des extrémités et des languettes avant et arrière qui sétendent vers le bas à partir de celle-ci. La bride inférieure possède des extrémités et des languettes avant et arrière qui sétendent vers le bas à partir de celle-ci. Lorsquelles sont assemblées avec les barrots de pont, les extrémités avant et arrière de la bride supérieure sont assises sur un rebord de support des barrots de pont avec les languettes reçues dans les fentes respectives. De façon similaire, les extrémités avant et arrière de la bride inférieure sont assises sur une patte inférieure des barrots de pont avant et arrière avec les languettes reçues dans les fentes respectives. Les supports dancrage coopèrent avec les barrots de pont afin de limiter laffaissement des ponts, tout en empêchant la torsion vers lextérieur de la bride inférieure des barrots de pont.

DETAILED DESCRIPTION OF THE INVENTION
[17] Referring now to the drawings, an exemplary embodiment of the
inventive
storage rack is generally indicated at 10 in Figs. 1-7.
[18] In the exemplary embodiment, the storage rack 10 includes four
vertical corner
supports 12A-D and a plurality of horizontal shelf assemblies 14A-E each
supported on
the vertical corner supports 12A-D. It should be noted that while the storage
rack 10 is
illustrated with five (5) shelf assemblies, the rack could also include fewer
shelf
assemblies or more shelf assemblies as the user desires.
[19] The vertical supports 12A-D in the exemplary embodiment are provided
in end
pairs (12A-B) (12C-D) with the respective paired front and rear supports
connected by
smaller upper and lower horizontal braces 16 and an angle brace 18.
[20] As seen in Figs. 1-7, each shelf assembly 14 includes front and rear
horizontal
deck beams 20 which extend side to side between and are supported by the
vertical
supports 12A-D, a plurality of tie supports 22 extending front to back between
the front
and rear horizontal deck beams 20 and a planar shelf 24 supported on the
interlocked
tie supports 22 and deck beams 20.
[21] Each of the deck beams 20 is generally C-shaped in cross-section,
having an
outer vertical side wall 26, a horizontal lower leg 28 extending inwardly, a
horizontal
upper leg 30 extending inwardly, and a horizontal support ledge 32 extending
further
inwardly from the upper leg 30 at a height which is below the upper leg 30.
(See Figs. 2
and 6). The opposing ends of each deck beam 20 include angle channels 34 with
hook
tabs (not shown) that are received into corresponding slots 36 formed along
the length
of the vertical supports 12.
[22] Referring again to Figs. 2 and 6, the support ledge 32 and the lower
leg 28 of
each deck beam 20 respectively include a plurality of aligned mounting slots
38 extending parallel to a longitudinal extent of the deck beams 20.
[23] Referring to Figs. 3-7, each tie support 22 is also generally C-shaped
in cross-
section, having a vertically extending side wall 40, a horizontal top flange
42 extending
3

CA 02856900 2014-07-15
P02841-US
,
inwardly and a horizontal bottom flange 44 extending inwardly parallel to the
top flange
42. The top flange 42 has front and rear ends and tabs 46 extending downwardly
from
the front and rear ends. Similarly, the bottom flange 44 also has front and
rear ends
and tabs 48 extending downwardly from the front and rear ends. Referring to
Figs. 3, 4
and 6 it can be clearly seen that the bottom flange 44 is slightly longer than
the top
flange 42 whereby the downwardly extending tabs 46 and 48 are horizontally
offset
from each other.
[24] When assembled with the deck beams 20 the front and rear ends of the
top
flange 42 are seated on the support ledge 32 of the front and rear deck beams
20 with
the tabs 46 received into the respective slots 38. Similarly, the front and
rear ends of
the bottom flange 44 are seated on the lower leg 28 of the front and rear deck
beams
20 with the tabs 48 received into the respective slots 38. (see Figs. 2, 6 and
7). As
illustrated in Figs. 1 and 2 each shelf assembly 14 includes a plurality of
the tie supports
22 extending front to back between the deck beams 20.
[25] When assembled, C-shaped cross-section of the tie support 22,
cooperate to
limit the sagging of the deck beams 20, while the interlocking tabs 46,48 and
slots 38 of
the tie supports 22 and deck beams 20 cooperate to prevent outward twisting of
the
bottom flange 44 of the deck beams 20.
[26] As best illustrated in Figs. 1, 6, and 7, the planar shelf 24 is
received and
supported on the support ledges 32 of the deck beams 20, and on top of the tie

supports 22 wherein the top surface of the shelf 24 is flush with the upper
surface of the
horizontal upper leg 30 of the deck beams 20 to form a continuous planar shelf
surface.
In the exemplary embodiment, the shelf 24 comprises a mesh configuration.
However,
any form of planar shelving material 24 would be suitable in the context of
the
invention.
[27] Additionally, it should be noted that while all of components in the
exemplary
embodiment are preferably fabricated from a rigid metal material to provide
the highest
rigidity and durability, any individual component or all of the components
could be
fabricated from other materials with similar effect.
4

CA 02856900 2016-04-18
21519-774
[28] It can therefore be seen that the exemplary embodiment provides a
unique and
novel storage rack 10, which is easy to assemble and which provides a high
degree of
strength. The unique tie supports 22 provide an improved level of rigidity to
the rack
structure and prevent unwanted sagging and twisting of the deck beams under
heavy
loading.
[29] While there is shown and described herein certain specific structures
embodying
various embodiments of the invention, it will be manifest to those skilled in
the art that
various modifications and rearrangements of the parts may be made without
departing
from the scope of the underlying inventive concept and that the same is not
limited to the particular forms herein shown and described except insofar as
indicated
by the scope of the appended claims.
